Silver Age fun

I knew of course about super pets, but I had no idea that there was a Legion of Super-Pets, consisting of Krypto, Streaky the Super-Cat, Comet the Super-Horse, Beppo the Super-Monkey (who had been used by Jor-El for rocket testing)and Proty II, a weird something that seems to be able to change its shape and looks kind of like the cross between a goat, a blop and one of those Enterprise aliens with antennae. (I've just seen a picture with a caption so I'm not sure exactly who/what Proty II is.)

If you want to look at Krypto, Streaky, Comet, Beppo and Proty II, here's a picture of them taken from the DC Who's Who Vol. 13:
